How to measure a profile tolerance
WebFirst, as you look at the drawing, you will notice that the profile tolerance is not associated with the basic dimension of 60 mm. Often I will see a profile tolerance next to a dimension which is totally wrong. Unless it is being used as a general tolerance, the profile tolerance must be directed at the surface being controlled as you see here. WebAny of the displacements in this animation represents a possible configuration for composite tolerancing with only primary datum in the lower segment. Note that the yellow and blue circles represent the tolerance zones with 0.5 mm and 0.1 mm diameters, respectively.

WebProfile of a line control tolerance in gd&t is a type of profile control tolerance. It simultaneously controls the size, orientation, location, and form of a feature. When applied to a surface, it specifies how much the surface can vary from its original cross-section. Don’t miss this article on the basics of Geometric Dimension and Tolerance. WebThe “profile of a line” control explains how to inspect to a profile, but it gives no information on what that profile is. In this respect profile of a line and profile of a surface are unique amongst the GD&T controls, in that all the others are self-contained; a cylindricity or flatness constraint needs no additional information, as the ...
WebHow to Measure it? For relatively simple profiles, you can measure the profile of a surface by moving the gauge at the controlled section when referenced to the actual profile. But for complex-profile, quality engineers use CMM, VMM, or 3D scanners. We will keep adding more information on the profile of surface control in gd&t.
